If quorum's child is broken, we can use mirror job to replace it.
But sometimes, the user only need to remove the broken child, and
add it later when the problem is fixed.

1. Rebase to the newest codes
2. Remove redundant codes in quorum_add_child() and quorum_del_child()
3. Fix typos and in qmp-commands.hx 
1. Rebase to the newest codes
2. Address the comments from Eric Blake
1. Remove the qmp command x-blockdev-change's parameter operation according
   to Kevin's comments.
2. Remove the hmp command.
1. Use a single qmp command x-blockdev-change to replace x-blockdev-child-add
   and x-blockdev-child-delete
1. Address Eric Blake's comments
1. drop nbd driver's implementation. We can use human-monitor-command
   to do it.
2. Rename the command name.
1. Don't open BDS in bdrv_add_child(). Use the existing BDS which is
   created by the QMP command blockdev-add.
2. The driver NBD can support filename, path, host:port now.
1. Use bdrv_get_device_or_node_name() instead of new function
2. Update the error message
3. Update the documents in block-core.json

Wen Congyang (3):
  Add new block driver interface to add/delete a BDS's child
  quorum: implement bdrv_add_child() and bdrv_del_child()
  qmp: add monitor command to add/remove a child
